The PPM-based method of [1]}. Since this approach does not analyze multiple series, we fit it to each series independently instead. The bcp package [2]} found in the R statistical software [3]} is used to implement this method. We referred to this method as the Wang method.

The method of [4]}. For this method, the two series are analyzed jointly. This method is implemented using the R package ecp [5]}. We referred to this method as the Matteson method.

The method developed in [6]} and [7]}. This method is our most natural competitor and is implemented using the ppmSuite R package. This method is referred to as the Loschi method. As for the Wang method, the Loschi method is fit to each series independently.
